Heat and cold shock test	-40°C30mins/80°C30mins, 50circles	Good
Impact resistance against shot-bag	GB-15763.3-2009	Qualified
Ball impact peeling resistance	GB*15763.3-2009	Qualified

    Laminating instructions:    1. Prepare and cut the EVA film into right size according to the following structure:        glass+EVA film + glass    2. Put the overlapped glass into silicon bag and seal  silicon bag well.     3. Activate vacuum pump for 5-8min till  vacuum value reach -0.095Mpa to double checking the vacuum is good.      4  Set up the laminating temp. and time  and start heating.The following data based on 4mm glass +0.40mm  EVA +4mm glass. Remark:  The above curves just for reference, the user should do some adjusts according to the process surroudings(temperature and humidity), glass area, glass thicknes,glass type and the machine itself.

	Temp	Time
1st heating step	60℃	20mins
2st heating step	130℃	45mins
cooling down stop vacuum	50℃
